Because of the washout, another AquaDam® had to be installed a week later. Step 1 is to make sure that the end of the AquaDam® is high enough up the bank so that it can inflate to 12' in height when completely full. The sides of the unit have been folded in prior to rolling it up on a beam. Three ropes are being used to restrain the unit from prematurely unrolling. Notice the water level upstream compared to the water level downstream. 

An 8' high AquaDam® has been installed on the upstream side of the 12' unit. This is the side that wasvdewatered to leave a dry work area. The 8' high unit does not go all the way up the bank so that trapped water may pass between the two units.

The two AquaDams® fit next to each other like a glove. The smaller unit lends support to the bigger unit.
